“Each individual has a characteristic profile,” explained Ian, holding a green rectangular box that looked like a TV remote control.

Using radio waves, you point it a wall and it tells you if anyone is on the other side.

“First, you can tell whether someone is dead or alive on the battlefield,” said Ian.

“But it will also show whether someone inside a house is looking to harm you, because if they are, their heart rate will be raised. And 10 years from now, the technology will be much smarter. We’ll scan a person with one of these things and tell what they’re actually thinking.”
